Hello, When computing an integral in parallel, I know one needs to scale things and do a global reduction. There are examples in previous posts (for example here ) with the integral of 2 vectors, say: Vh<complex> scaledVecu = Vecu; for[i, v : A.D] scaledVecu[] *= v; complex wrong = int2d(Th)(scaled…

I see. Only one of the term has to be scaled.
